A master's thesis at the University of Basra investigated the manufacturing and performance evaluation of a subsurface organic fertilizer application machine using a screw conveyor.

The thesis, submitted by researcher Bashir Nayef Daham, aimed to manufacture a subsurface organic fertilizer application machine using a screw conveyor and to evaluate its field performance.

The study included evaluating the field performance of the locally manufactured machine and testing its efficiency under the study conditions.

The study recommended further research to manufacture or develop organic fertilizer application machines to support the agricultural sector.
